passed the boundary between the two counties. Winnesheik and Allamakee 

 counties. 



{16)—AcGipUercooperi. . COOPER'S HAWK. 



Apparently not so abundant as the foregoing, and confined more to the 

 timber area. Three young and an addled egg were taken from a nest at De- 

 corah. Winnesheik and Allamakee counties. 



{17)—ButeshoreaUs. RED-TAILED HAWK. 



Quite common throughout the valley. Not a day passed but what a num- 

 ber of these birds were noticed. Several young and adults were shot from the 

 boat. Winnesheik and Allamakee counties. 



il8)—Bitteo lineatus. RED- SHOULDERED HAWK. 



By no means as common as the last. Allamakee county. 



U9)—Buteo latissimus. BROAD- WINGED HAWK. 



Several of these birds were seen but none secured. Winnesheik and Alla- 

 makee counties. 



{20)—Haliactus leiicocephalus. BALD EAGLE. 



A bird, which I took to be of this species, was seen flying about a cliff' on 

 June 28th, in Allamakee county. 



{21)—Falco peregrinus anatvum. DUCH HAWK. 



A pair of birds which I am inclined to refer to this species were noticed 

 sporting about one of the steep escanpments. The graceful swift movements 

 and size cause me to believe that it must have been this master, as he is the 

 only one able to perform such feats of wing. Allamakee county. 



(22)—Falco spavarius. SPARROW HAWK. 



Not common in the valley proper ; only a few observed and these frequented 

 the more exposed situations. Winnesheik and Allamakee counties. 



(23)— Bubo virginianus. GREAT HORNED OWL. 



Quite common ; a young bird whose head was still covered with down was 

 shot. The birds keep close to the water and on several occasions I flushed them 

 in early morning from fallen trees which extended into the water. The fact 

 that this happened repeatedly led me to believe that Bubo might at times vary 

 his diet by catching a fish. Is it not possible that the fish might be attracted by 

 his glowing eyes ? Winnesheik and Allamakee counties. i 



{24)—Symiunv7nehulosum. BARRED OWL. 



Seems to be more restricted to the hills and hill-sides. Winnesheik and 

 Allamakee counties. 



{25)—Megascops asio. SCREECH OWL. 



The querulous wailing note of this bird was heard many an evening in our
